rvilbert 9 Posted September 25, 2020 Posted September 25, 2020 Good evening, I apologies for the broadcast message but i have decided to reinstall my Hackintosh machine using Catalina 10.15.6 and .... I'm stuck at "PCI configuration begin".. My configuration is: Asus X99 Deluxe Core i7 5960x 32 Gb memory GTX 980 Knowing that my graphic card would not be fully recognised in Catalina i have also tried to install High Sierra but I managed to get exactly to the same point and i have therefore decided to give another try to Catalina and .... I'm still stuck. (FYI I had managed to install 10.8 on my machine a while ago but a few things have changed since then and I may be missing a trick). In a nutshell I believe my issue is linked to this message that i'm getting: Waiting on <dict ID="0"><key>IOProviderClass</key><string ID="1">IOResources</string><key>IOResourcesMatch</key><string ID="2">boot-uuid-media</string></dict> I tried all options (with/without flags and with/without kext) but i think that my issue is between my DSDT, SSDT and config.plist files. Any help would be much appreciated! I have attached my EFI folder and the print screen with the error message. Let me know if you need any further information. Thanks a lot EFI.zip Share this post Link to post Share on other sites
spakk 1,839 Posted September 25, 2020 Posted September 25, 2020 add npci=0x2000 or npci=0x3000 to your boot flag and then it should work. Share this post Link to post Share on other sites
